Richard A. Register, Eugene Higgins Professor of Chemical and Biological Engineering, has been elected as a Fellow of the American Institute of Chemical Engineers (AIChE), as approved by the AIChE Board of Directors at their September meeting. As described in AIChE's Constitution and By-laws, election as Fellow—the highest grade of membership— “shall be recognition of professional attainment, and significant accomplishment in engineering.” Register will be recognized

Richard A. Register, Eugene Higgins Professor of Chemical and Biological Engineering, and Emily A. Carter, Gerhard R. Andlinger Professor and Associated Faculty in CBE, were named Fellows of the American Chemical Society (ACS) this week. The ACS Fellows Program was established “to recognize members of ACS for outstanding achievements in and contributions to Science, the Profession, and the Society.” Register was recognized for co-inventing block copolymer lithography, &nb

Recent collaborative work from the groups of CBE Professors Ilhan Aksay, Bob Prud’homme, and Rick Register has shown that functional graphene sheets (FGS) make effective multifunctional nano-fillers for several types of elastomers, simultaneously improving mechanical properties, reduce gas permeation, and impart electrical conductivity. This combination of property improvements is unavailable in any other filler, including carbon black and nanoclay, and result from the high aspect ratio an

CBE graduate student Sheng Li and Professor Rick Register, studying materials synthesized by alumna Sasha Myers *08, have recently uncovered an unexpectedly broad range of nanoscale structures in polymers containing chemically dissimilar crystallizable blocks. Moreover, the structure can be tuned either through synthesis (total and block molecular weights), or through processing (such as crystallization during fiber drawing or quiescently). The latter aspect of this work was featured

An example of nanofabrication through the replication of a block copolymer thin film template. Top portion of the image shows an array of gold dots, 30 nm diameter and 18 nm thick, on a silicon wafer substrate. The lower potion shows the mask through which these dots were deposited: a 10 nm-thick silicon nitride membrane, perforated with holes of 30 nm diameter.

X-ray diffraction pattern from a newly-synthesized diblock copolymer containing a linear (high-density) polyethylene block. As designed, the material self-assembles into a lamellar nanostructure, with layers of polyethylene alternating with layers of glassy polyvinylcyclohexane. Macroscopic alignment of the structure was achieved by planar extensional flow in a lubrication channel die.

Almost 1,000 middle school students and teachers from Mercer County schools flocked to Princeton University to explore cutting-edge science and technology with university researchers during a campus-wide exposition on March 17. Among the presenters was Professor Rick Register, who explained to students the changing properties of molecules using bouncing rubber balls and dry ice. Also involved was postdoctoral student Steffen Berg, who used a soap bubble machine to illustrate some features of the
